ATTACHMENT FOR THE LEGS OF BILLIARD-TABLES.

Specilication forming part of Letters Patent No. 5,3l3, dated September725, 1866.

To all whom t may concern Be it known that I, WILLIAM B. SomvrEILf ing apartof this speciticatiomin which- Figure l represents a section cutthrough the base-screw, plate-nut, and washer. Fig. 2 shows an undersideview of the supportingbase. Fig. 3 shows-a hook-lever or wrench for Fig.4 is a view of a doubleprong wrench and handle for the same purpose.

The object of my invention is to support,

. elevate,and level up billiard-tables, platforms,

or other heavy articles that require nice adjustments, which may bedonein the most perfect and easy mannerv by the use of lny iinprovedelevator.

My invention consists in a broad, circular metallic base, having ahollow center-pillar, on which is a substantial screw-thread, to whichis Iitted a plate-nut, with one or more square notches or recesses inits edge to receive a hook-lever or a single or double prong wrench, andafriction-plate above it; also, in having a recess under the bottom ofthe base, into which a disk of vulcanized,india-rubber is secured, forthe purposes hereinafter described.

To enable others skilled in the art to make and use my invention, I willdescribe it more fully, referring to the drawings, and to the lettersmarked thereon.

The base A may be made of 'cast-brass or other suitable metal, in thebottom of which is a recess in which I secure a ring of sheet vulcanizedrubber, B, to form the step or bearing on the floor. rIhis-prevents anynoise or jar, and forms friction enough to hold it in its place andprevent it from turning as the platenut C is being turned up or vdowu onthe screw a of the hollow pillow D, the plate-nut O being ofconsiderable dimensions, so as to have a substantial bearing on thefrictionvplate E, which is placed between it and the table-leg, or thearticle it is placed under, for the pur,- pose of elevating or levelingup..

In the periphery of the plate-nut C there may be one or more notches, e,into which the nib or square hookfof the wrench F is inserted to raiseor lower the nut C, for the purpose of leveling up billiard-tables, orelevating and adjusting anything to a nicety.

Having thus described my invention, what I claim 'as new, a n d desireto secure by Letters Patent, is-

l. rlhe combination of the vulcanized indiarubber or other equivalentsubstance for a step, with a metallic base, hollow-screw pillar,plate-nut, and friction-disk, substantially as and for the purposesherein set forth.

2. In combination with the device above described, thc doublearniednib-Wrench or handlever for operating the same, in the manner and forthe purposes specified.

In testimony whereof I` hereunto set my hand on this 28th day of August,1866.
